By the time a Kaufman County sheriff's deputy reached the site of a Tuesday morning crash, several drivers had stopped to help.

A truck had rear-ended a tractor-trailer outside Terrell and was still pinned underneath when Deputy Conner Martin arrived at the scene.

Body camera footage released by the sheriff's department Wednesday shows over a dozen people surrounding the burning truck, with some trying to pull the driver from the smoke-filled cab.

The deputy climbed into the truck with the bloodied man, who was trapped in his seat by the crumpled dashboard. As smoke blew in through the shattered windshield, Martin had to duck out for air several times.

Flames erupted from under the car's hood as Martin freed the man's leg and bystanders pulled him to safety.

The driver was airlifted to a Dallas hospital, where he underwent surgery and treatment for his burns, family members posted on Facebook.
